Robert, remember you have retentive and non-retentive ferromagnetic so, with that piece of magnetic graphite and if you can attract steel or iron it is retentive. Depending whether it is retentive or non-retentive you can experiment with it and lay it on a graphene sheet and then apply voltage to the graphene sheet to see if the piece of magnetic graphite changes back to non-magnetic or diamagnetic graphite.

Do magnets pick up the powder itself? Or just the painted paper? Big question: what's the curie temp of your magnetic graphite paper? If it's up in hundreds of C deg, maybe paint it on ceramic, or ceramic fabric. That way it can be heated to where the attraction to magnets disappears. Also, if successfully heated past a temperature where it loses the magnetic attraction, does the attraction-effect reappear when cooled again?

Hi Robert, I've enjoyed watching your videos for over a year now, and have even tried my hand at a couple of experiments with graphite and graphite oxide. I noticed you're using a Zoom H4n Sound Recorder there, I shoot film and video, and I own two of those. Fantastic choice for a sound recorder! Might I point out that if you're recording in stereo front mode (red LED at the top facing the front face of the unit, then you should rotate the microphone so the screen is facing you. There are 4 microphones in there, both in xy pattern, and the pairs are meant to capture sound in ~45° area in front of it (the back stereo mode is ~120° wide area, so less ideal for capturing a single subject) Also, I understand if you don't want to risk damaging the recorder but the closer you have that thing to your mouth, the lower a gain setting you can set, which will help to cut a lot of the reverberations and echoes from your lab. Cheers!

When making permanent metal magnets they pass an electric current through them to align the molecular structure. Maybe the process of making the ink and letting it dry has somehow aligned the molecules in the graphite. This could either be because of the earth magnetic field or some magnetic field around your work bench. One easy way to eliminate the workbench is to paint another peace somewhere else. Just a theory of course :-)

Was wondering what 7 years of research later might come up with and I found Interesting research related to this. It appears that ordinarily undetectable trace amounts of iron particles in carbon are pushed closer and closer together by the mechanical process you've performed. The more you compress them the bigger the magnetic field you can create. That's the theory of the research anyways. This of course isn't definitive just interesting that this is still some rather cutting edge research as it relates to the next level of super-computing.

I'm guessing the glass balls/rubber and water combo is producing a static charge when agitated over a long time. Graphite being conductive absorbes the charge and orientates itself into grain structure like a heat treating on a metal or the domain's in a magnet which are pretty similar. Once bound into the ink and left to dry, the bunched together masses align naturally and combine to produce a feild? Electric charge in water sounds like hydrogen has something to do with it aswell, usual surprising hydrogen stuff Probably waaaay off but its late and I'm bored 😄

It seems the idea was developed since 2015ish and a Chinese corp Dongxu made a prototype on July 2016. Also saw that there are startup cloud funded company such as zapngo and so on (MWC 2016). 2. Continuing to the first question, what is the reason that makes it hard to make it commercialize. It said its cheap and easy to make. 3. According to some research on Graphene battery, Is it possible to make the capacity of the battery 100 times bigger with the same size to lithium battery (aka cellphone batteries)?Thanks Will keep watching

Hi Robert! I would be honored if you go ahead and show the world how we make superparamagnetic graphene, amorphous carbon, and graphite! You still remember how I discovered the process a couple years back don't you? It would be great if you mentioned my name in a little attribution in the video. Thanks Robert. I can't wait to see the things this knowledge brings about, once everyone starts experimenting with these superparamagnetic carbons. Also when you perform the process, I have found that quartz crucibles are about the only vessels that can withstand the temperatures without breaking. I've tried Vision Ware, but it absorbs too much energy to allow the carbon to reach the plasma state.

I've never heard of this before. After watching, I searched "is carbon magnetic" and the first result was this VERY INTERESTING article: www.materialstoday.com/carbon/news/magnetic-carbon/ They are saying, among other things, that graphite which has been irradiated with protons (hydrogen atoms) can have a very high magnetic moment. Here is a computer graphic simulation of doping the carbon lattice with hydrogen: kzitem.info/news/bejne/r6OGp3WlcJGpjGU Great visualization! Maybe there is some "hydrogen doping" going on from just being in air, or your solution, and tumbling. Or maybe it's picking up hydrogen from the rubber... or something from the glass (is it borosilicate?)... or maybe you were right, and it's a result of the physical change. Very interested in hearing results of an analysis of the material. Thanks for another thought-provoking video.

I randomly remembered this topic as I also made some magnetic graphene a few years back (video on my channel) Do you know if there has been any research explaining this phenomenon? I'm kind of leaning towards the theory that there is some iron contamination. In my case the graphene only became magnetic after heating it so maybe some reaction or reordering is necessary.

crazy if so...I thought this tech could only be created with some highly expensive tools and equipment (and what wizardry they'd carry out to achieve those ) :o so I suppose the mystery is so big that you will have to have it checked :)

Lol, I had the same thought. I couldn't help but cringe a bit every time Robert waved his hands over the cup. However I often drink coffee or tea at my own desk/lab, which also freaks me out a bit (only if I'm doing chem experiments tho), so I can't complain to much!

But even worse than simple proximity? Most of my experimental beakers are actually reused mason jars, and if all the mugs are dirty, I also sometimes drink out of... mason jars! :O yeah not being able to tell the difference between my coffee mug and my reaction beaker is insanity.

Have you ever had any iron in that ball mill, because if you have you may have contaminated the graphite with iron.

I have a theory based-upon what research has shown to be the prior causes of magnetism exhibited in graphite: www.iop.org/news/12/jan/page_53593.html When the graphite used in the experiment (like most graphite with impurities) is spun in the 'Ball Mill', Fe particles are moving past the electro-magnetic fields of the machine's motor and my hypothesis is that they have become magnetized. (James Cole was perhaps onto something?...). I'd like to know how the graphite was sourced. And I noticed this video began with a RMS's disclaimer on the many different types of graphite, categories, what it means to be Graphene. And essentially what I gather is that is all comes-down to purity. If ferro-magnetic particles already were present in the graphite powder, then spinning them over-time would cause those particles to allign N-S-N-S.... and result in a cululative-sum magnetic-field of all of those particles at a single-point (like a kitchen-magnet). Assuming that the graphite was tested for purity prior to the experiment and had no ferrous-magnetic material, It would be good to test for magnetism in/near the Ball Mill chamber when the electric-motor is running, or repeat the experiment by hand and not in the presence of EMF. Would be interested in a follow-up to this, really dig RMSs videos as he inspires us to explore and discover. I think a bigger question is can pure Graphene be magnetized (if in the right state, right temp, etc... :). What also comes-out of this is perhaps a method to determine the level of Fe impurity within graphite or perhaps a method to isolate and remove them! Thanks RMS for your spirit for science and discovery, you inspire us all!

It all about purity structure and simplicity mate the graphite tests out at 99.9997% carbon on elemental analysis - provided by the supplier by the way and it's all about us all being involved

I've come up with a new scheme for graphitization. . . I am going to try making an edison style bulb in a mason jar held under vacuum, with a piece of conductive charcoal as a 'filiment' held between two tunsten rods. Already assembled one and tried it not under vacuum (couldn't wait for a new vacuum pump), and it definitely lit up and became more conductive, but of course burned up after a couple of minutes. Do you figure that Edison was actually turning his bamboo into graphite? The ultimate way to do this would be with an induction coil around the vacuum chamber for a cold levitation, but that is more project than I want to take on at the moment, and the power consumption would be prohibitive. Have you ever looked into/thought about liquid phase carbon? I have been wondering about iodine, carbon, etc as a liquid. . . About to do some research on it.

Apparently carbon can take on a liquid phase of sorts, but only at very high temperatures and pressures. . . Presumably something like that takes place when graphite is turned into diamond, interesting that a CVD chamber can also create diamond in near vacuum though. Makes me wonder if there might be a way to trick it into staying liquid.
